To all whom it may concern:

it known that I, JOSEPH H. Dicnmson, a citizen of the United States, anda resident of Montclair, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Portable Cableways,of which the following is a specification.

My present invention relates to the improved portable cableway-and hasparticular application to an apparatus of the type referred to adaptedespecially for logging operations.

In carrying out the present invention it'is purpose to provide a specialcableway Wll ch may be moved from place to place as the occasion mayrequire, without i e-rigging thespars and the like.

It is .also my purpose to provide an improved cableway having asupporting spar for the various ropes employed, so that the entireapparatus may be readily and speedily moved along the track from placeto place, this being an advantageous feature when logging in mountainousdistricts where it is oftentimes inconvenient or impossible to em ploy astanding spar, such as an adjacent tree.

A further object of my invention is to provide means by which the guysfor the spar may be readily tightened and loosened as necessary, and Ialso lead or direct said guys in such a manner as to obviate thepossibility of the guys interfering with the various leads of the ropesof the cableway, such as the'.skidding ropes, the carriage-actuatingropes, and the like.

By means of my improved construction, I also dispense with theemployment of a large gang of riggers, as it is unnecessary to re-rigthe head, or portable spar every time the cableway is moved, as is thecase Where permanent supports are employed.

A further purpose of the invention is to so mount the head spar upon theframe of the machine that it may be readily raised and lowered, thisbeing a valuable feature when the apparatus is moved from place toplace, as the tower may be lowered toward the frame, thereby obtainingalow center of gifavity for the machine. 7 v

'With these and other objects of a similar naturein view, 111 inventionconsists in the construction, com motion and arrangement of parts'setforth in and falling within the scope of the appended claims.

In the accompanying drawings, Figure l is a View in side elevationshowing one embodiment of my apparatus; Fig. 2 is an end view, the ropesof the cableway being removed, said view showing means for controllingthe guy ropes running down through the center of the spar; F 2 is adetail of the preferable form of joint to permit the spar to yield inany direction; Fig. 3 is another view in side elevation of the cable wayapparatus embodying my improvements in slightly modified form; Fig. lisan end view of the machine shown In Fig. 3, the cableway apparatus beingomitted, showing guy ropes passing down through the spar, and also theoperating drums 27, 27 with their ropes to raise and lower the spar;Fig. 5 is a plan View of the top of the supporting spar and showing themanner of supporting the guys at such. point; Fig. 6 is a crosssectional view taken through a portion of the tower on the line G6 ofFig. 4, showing the circular attachment which allows theautomaticadjustment of the main cable and lead blocks in any desireddirection around the spar.

Referring now to the accompanying drawings in detail, and especially toFigs. 1 and 2,-A indicates a frame or platform of the machine providedwith suitable supports 5, adapted when the machine is in its stationaryposition to straddle the track. 6 designates jacking means for raisingand lowering the frame upon a logging car B for transportation. Carriedby the platform A is a supporting vertical framework 7, of any suitabletype carrying the swinging or pivoted spar 8, the latter being fulcrumedas at 9, upon the support 7. The manner of pivoting the spar is moreclearly shown in Fig. 2,-in this instance, suitable bearings 1O, 10being secured to the supporting frame 7 and Within said bearings lie thetrunnions 11, ll of the spar, said trunnions being so socketed in theirbearings as to permit the tower to have a slight play or movement at thetop in any direction, so that the unequal strain of the guys may becompensated for. Upon the frame A is mounted an engine designated as anentirety by the letter C, said engine being of any Well known andapproved type, such as the Lidgerwood engine, and embraces in itsconstruction a plurallty of drums for operating the various ropes of thecableway. As this engine is of a well known construction it isunnecessary to de- Q i I 936,425

scribe the same in detail here, the illustration in the present drawingbeing merely conventional. The cableway itself 1s also oi a well knowntype, a designating the main cable secured in a manner hereinafter de:

(Zindicates the onthaul rope. for the carriage, c is the inhaul, or whatis commonly known as the skidding line, and f designates what iscommonly termed the slack-pulling line employ ed to overhaul theslack-pulling drum on the carriage to permit the lowering of thefallrope g carrying the grappling tongs or logeneaging means it. Theline (Z is operated by the drum 2' of the engine C, the line 0 by thedrum 7' of the engine and the line f by the drum 7c. D indicates asecondengine mounted upon the frame, said engine in this case being providedwith 'lhree drums. The drum Z operating the line 12, this line tuningover a pulley 12 attached to the spar. This line [2 is employed forchanging the main cable "from one setting to another. Upon the forwardshaft in are mounted two drums a. a, side by side, one of said drums, anordinary slip drum, controlling the heel-block line 13, which runs oversuitable pulleys 14, 15 and 16. and operates the block and fall 0. Thisline may be termed the heel-block line and serves as a tension means inconjunction with the block and tall for 'tensioning the main cable. Sucha tension device is shown in an earlier patent to Miller & Dickinson No.8 52%, and it is unnecessary to further describe the operation of thesame here. The srcond drum n is employed for operating the car-spotting,line 17, this line when not employed. for spotting the cars beneath theloader is preferably connected to the lower end 18 of the tower andmaybe employed to assist in raisingand lowering such Carried preferablyat the forward end of the frame is a. turntable E carrying a. thirdengine F, said engine having suitable drums/p and operating the loadingline r and the swinging lines a respectively. b'nch construction isshown in the patents to Miller LQ7 I)iCklllSOll No. 726,325. dated April28, 1903, and need not be described here further in detail.

When the tower is in its elevated position, as when the apparatus isemployed in the actual operation of logging .it is, of course, necessaryto guy or secure the tower against movement and in the present invention1 have shown a novel form of guy lead. Reterring', tor instance, toFigs. l and 9., l provide a suitable number of guys 15) which, for thesake of convenience and distinction, may be termed ground guys; that isto say, the lower end ot' said guys are secured to suitable points ofsupport as the stump :20, while.

l i l the upper ends of said guys pass over sheaves '21 jonr aled in thecollar 22, adjacent to the top of the spar, said guy ropes then. leadingdown through the interior of the tower and over suitable sheaves 23 tomtheir respective guy tightening drums 24;, in the present instance,mounted on the sup porting frame 7 and designed to be open ated by hand,although I Wish it to be understood that I may extend said guy ropes topower operated drums mounted at any suitable position, either upon theplatform or frame, or upon other portions of the apparatus.

The advantages incident to the construcso tion of apparatus shown inFigs. '1 and 2 will be readily apparent. The spar or tower may be easilyand readily raised and lowered by the means described and when. 10weredfor transportation, may rest or lie above the loading boom, andfurthermore, the arrangement of guys shown, that leading such guys intoand down through the spar enables me to obtain a universal lead of thevarious operating ropes of the o0 rableway; that is to say, said guysare located in such position that while inaintain ing their etliciencyas supporting means, they do not interfere with the operation of thecableway ropes.

In Figs. 3, 4, and'G I have shown a slightly modified form ofarrangement as concerns the raising-and lowering of the tower, the tower8 being provided at its fulcrunnal point with a bull-wheel 25 actu- 10'satcd by a rope '26 operated by suitable drums 527, said rope passingover suitable guys 28 to obtain the correct lead. In raising andlowering the construction of tower shown therein the operation will beapparent. When the drums 27 are rotated in one direction the bull-wheelis actuated to lower the tower and when rotated in the opposite (ii--rection to raise the latter.

While I have herein shown and described preferred terms of my invention,1 Wish it to be. imderstotal that I do not limit myself to all theprecise details of construction herein delineated, but that modificationand Variation may be made without departing from 11-5 the spirit of myinvention or exiceeding the scope of the claims.-
